AD822 is quite old (1995 I think), I wish to find replacement of more modernise version.Please don't ask me why(!)
The key parameter is +5V, FET/CMOS, low frequency, low gains circuit (noise not important), good rail to rail, good I/P range to GND and bit below. SMD package as usual, maybe better offset and drift spec.
Any suggestion for 5 units to choose from and why?
I wish to use it for rectifier circuit, I have input signal from 5mV to 2Vpp
